System and method for inferring or prompting HVAC actions based on large data standard deviation based metric

The present disclosure relates to a computer based system for collecting, analyzing and presenting temperature information from sensors associated with an HVAC system. The system makes use of a processor for communicating with the plurality of sensors and obtaining temperature data reported by each of the sensors. A graphical user interface (GUI) module is provided which is embodied in a non-transient medium and configured to run on a computing device having a display screen. The user GUI module uses the temperature data, in real time, to generate a graph on the display screen. The graph includes a plurality of components each having different indicia to indicate groups of sensors that are below a predetermined lower temperature limit, above a predetermined upper temperature limit, and within a predetermined temperature range. Standard deviation information may be supplied with the graph which relates to the maximum standard deviation of those groups of sensors that are reporting temperatures above and below the predetermined temperature range.
